Abstract
Outbreak response to quarantine pathogens and pests in the European Union (EU) is regulated by the EU Plant Health Law, but the performance of outbreak management plans in terms of their effectiveness and efficiency has been quantified only to a limited extent. As a case study, the disease dynamics of almond leaf scorch, caused by Xylella fastidiosa , in the affected area of Alicante, Spain, were approximated using an individual-based spatial epidemiological model. The emergence of this outbreak was dated based on phylogenetic studies, and official surveys were used to delimit the current extent of the disease. Different survey strategies and disease control measures were compared to determine their effectiveness and efficiency for outbreak management in relation to a baseline scenario without interventions. One-step and two-step survey approaches were compared with different confidence levels, buffer zone sizes, and eradication radii, including those set by the EU legislation for X. fastidiosa . The effect of disease control interventions was also considered by decreasing the transmission rate in the buffer zone. All outbreak management plans reduced the number of infected trees (effectiveness), but large differences were observed in the number of susceptible trees not eradicated (efficiency). The two-step survey approach, high confidence level, and the reduction in the transmission rate increased the efficiency. Only the outbreak management plans with the two-step survey approach removed infected trees completely, but they required greater survey efforts. Although control measures reduced disease spread, surveillance was the key factor in the effectiveness and efficiency of the outbreak management plans.

新植物病害爆发管理计划的绩效:Xylella fastidiosa 在西班牙大陆引起的杏叶焦枯病案例。
欧盟植物健康法》规定了欧盟(EU)对检疫病原体和害虫的疫情应对措施,但对疫情管理计划的效果和效率进行量化的程度有限。作为一项案例研究,我们使用基于个体的空间流行病学模型对西班牙阿利坎特疫区由 Xylella fastidiosa(Xf)引起的杏叶焦枯病的病害动态进行了近似分析。根据系统发育研究确定了疫情爆发的时间,并利用官方调查划定了当前的疫情范围。对不同的调查策略和疾病控制措施进行了比较,以确定它们与没有干预措施的基线情景相比在疫情管理方面的有效性和效率。比较了采用不同置信度、缓冲区大小和根除半径的一步法和两步法调查方法,包括欧盟针对 Xf 立法规定的方法。通过降低缓冲区内的传播率,还考虑了疾病控制干预措施的效果。所有疫情管理计划都减少了受感染树木的数量(有效性),但在未根除的易感树木数量(效率)方面却存在巨大差异。两步调查法和高置信度提高了效率,同时也降低了传播率。只有采用两步调查法的疫情管理计划能完全清除受感染的树木,但它们需要更大的调查力度。虽然控制措施减少了疾病传播,但监测是影响疫情管理计划有效性和效率的关键因素。
